From: Dave Airlie <airlied@xxxxxxxxxx>
just adds some unchecked ioctls to setup the nodes.
Signed-off-by: Dave Airlie <airlied@xxxxxxxxxx>
v2: - original ioctl numbers are now taken, use next available
- resolve some trivial conflicts due to bit-rot that
occurred since the original patch was created
v3: - added planes to ABI to address a comment from Ville Syrjala
